I am building a 1976 Pontiac Le Mans. Its got around 400HP and am wondering for the 1/4 mile what kind of tranny should I use. I want to put and Automatic in it, but my friends say that I am an idiot that Manual is the best way to go?? What should I do?? What do the PRO's use? Any help appreciated. Thanks

small, strong autos are the way to go. They will keep up with sticks and in some cases outrun them. You dont need to worry about missing gears or non of that bs.If its race only remember to get a good valve body, converter, and strong internals along with a race shift kit. I would recommend a C4, TH350 or something similar. you will see less power loss with these as compared to a C6 or TH400 even though they are stronger.

I'd say TH350 get a built one w/ shift kit.Match your stahl converter to the car.Evan a trans break will help with luanch.
If the car is light a power glide would be good.Stick trannys are alright but there to inconsistant for bracket racing.An auto will shift quicker,more precise(no missed shifts),And can luanch just as good w/ the right converter.
